Backflow Testing & Certification Services in Columbus, Ohio

Certified Backflow Testing to Protect Your Water Supply

Backflow testing is a mandatory annual requirement to ensure that your drinking water remains safe from contamination. If your backflow prevention device hasn’t been tested or certified, you risk water shutoff by local authorities.

At The Waterworks, we provide certified backflow testing, certification, and repairs for homeowners, businesses, and municipal facilities across Columbus and Central Ohio. Our team ensures that your backflow preventers comply with all local and federal regulations, keeping your water supply safe and contaminant-free.

What Are the Legal Requirements for Backflow Testing?

Federal and Ohio state laws require that all backflow prevention devices be tested annually by a certified backflow tester. These regulations help prevent contaminants, pesticides, and chemicals from entering the drinking water supply.

If your backflow device is not tested, local authorities may shut off your water supply. Each device has a unique serial number for tracking, and all testing and repairs must be completed by the property owner.

At The Waterworks, we make the process easy and hassle-free by handling:

  • Certified backflow testing
  • Official documentation & compliance reporting
  • Backflow device repairs and replacements (if needed)

We provide same-day testing and repairs, so you can stay compliant and keep your water safe.   

Why Is Backflow Testing Important?

Backflow prevention devices protect public and private water supplies from contamination caused by:

  • Pesticides & Fertilizers from irrigation systems
  • Chemicals & Industrial Waste from businesses and manufacturing facilities
  • Sewage & Wastewater from damaged plumbing lines
  • Fire Suppression Systems that can allow stagnant water to enter drinking supplies

Benefits of Annual Backflow Testing

  • Protects your home or business from water contamination
  • Prevents serious health risks from chemicals & bacteria
  • Ensures compliance with Ohio state and federal regulations
  • Avoids costly fines or water shutoffs

If you have a sprinkler system, irrigation system, or fire suppression system, backflow testing is required to prevent contaminants from entering the municipal water supply.

What Is Backflow & How Does It Happen?

Backflow occurs when water flows in the opposite direction than intended, allowing contaminants to enter the clean water supply. This typically happens when there is:

  • A sudden drop in water pressure (such as a water main break or high demand)
  • Cross-connections between potable and non-potable water sources
  • Improperly installed backflow preventers

A properly installed backflow preventer acts as a barrier, stopping pesticides, chemicals, and waste materials from contaminating your water supply.    

What Happens During a Backflow Test?

During a backflow test, The Waterworks’ certified technicians will:

  1. Shut off the water supply to inspect the backflow prevention device.
  2. Check test cocks and shutoff valves to ensure proper function.
  3. Use specialized pressure gauges to measure differential pressure readings.
  4. Identify leaks, pressure issues, or faulty components.

If any issues are detected, our team can immediately perform the necessary repairs—saving you time and money.

Unlike some companies that only certify devices, The Waterworks provides both testing and repair services in a single visit.

I have been a Jonle regular for a lot of years. I actually have never been disappointed by any of the techs Jonle have sent. They are polite trustworthy types. When Cory was finished with the service, he asked there was anything else he could do for me before he left. I asked about the basement lights being off. He let a light on that was on when he went down. He ran back downstairs for me and turned it off. Not a service requirement. But it is something a nice guy does for an getting older lady.

I was impressed but this company. They got here quick sent a text with technical's picture saying he was on the way. Since my husband couldn't be here it made me feel safe just knowing who was coming. Matt was very professional and nice took time to explain the issue with our boiler system along with pictures showing the damage. Waiting on estimates for part replacement versus replacement of boiler. Great job that's for going above all rest. The picture text A+

Waterworks has been my go-to for years, and they consistently deliver excellent service. Easy, timely scheduling, and they always send experienced, knowledgeable professionals who take the time to thoroughly explain what's going on and walk me through my options. I especially appreciate that they don't just fix the issue - they take the time to answer my questions and provide guidance so I can maintain things myself going forward. They stick to their original quotes when things become more complicated and provide options to manage my costs (e.g. order a part myself.) I had two services in the past two weeks: a kitchen sink installation that required reconfiguring and replacing all of the hardware underneath, and a toilet repair for which the part was not available, but the rep helped me order the correct part and provided enough instruction to install it when it arrives.

My experience with The Waterworks has been very good. Michael assessed my plumbing issues and made necessary repairs. I really appreciated the fact he pointed out that I didn't need the service I thought I did. Thus, I was not overcharged. I recommend The Waterworks if you need plumbing service.

Chris showed up 2 hours early (after a courtesy call). The service call was not needed as it was my own naivety that caused this situation. Chris clearly explained the dilemma and was out the door in 20 minutes. This is not the first time that I have had Water Works out to my house and it WILL NOT be the last. SUPER company!

We thought our sump pump had failed and needed to be replaced. Tech showed up on time and found that the breaker had been flipped. No pressure to purchase something we didn't need....he just flipped the breaker, told us that was what was wrong, told us he turned it on and confirmed the sump pump was working and left. Great experience! Will definitely call them again if we have another issue!

John came out for preventative maintenance on my sewer line because of a tree in my front yard always having roots entering the line and causing backup. He did a great job and sent his 6 inch blade the full 90 feet to clear the line.

Quite possibly the most detail oriented company I’ve worked with. The way their HVAC installer made sure every wire was secured in brackets and everything was run neat and tidy really tingles all the OCD tendencies one may have. Overall I couldn’t have chosen a better company to work with!

We called a few plumbers for the same issue at Horizon High School. They all came, inspected the problem, and left after giving us repair quotes. Thomas from Water Works was different. He carefully examined the issue, explained how the system works in detail, and offered a very effective solution. He didn’t just give us a quote — he took the time to help us understand the problem and then fixed it properly. We truly appreciated his professionalism, knowledge, and clear communication. Highly recommended!

The whole experience with Waterworks was positive. I called during the weekend and spoke to a representative and scheduled a service call for Monday. They arrived at the time that was promised and a call was made 30 minutes prior to arrival. The technician was courteous and explained what potentially could have occurred and what options I would have. Service call was completed and I am very satisfied with the entire process.

Will was very professional. He updated me on all the things he was doing to diagnose the problem. I felt he went over and beyond. He knew I was concerned about the cost and for some reason I did not renew my Silver Plan. In the past month I had to get a new water heater, my fireplace went out and today I needed to get new glasses. Being on a fixed income is worrisome. I was happy though with the service I received.

JonLe was awesome to work with they didn’t hassle us during the buying process or make us feel rushed, they gave us time and space to figure things out and let us know if we had questions we were free to ask. Makes it easier when making a huge purchase for your home. We were able to call and schedule the new HVAC install quickly and they work efficiently and left everything clean and tidy when done! They explained everything to us when they finished the install and let us know all the important details and what to expect. I would highly recommend JonLe to anyone in need of a new HVAC system! They also had very easy finance options for the system which was also nice to see.

We’ve been loyal JonLe customers since 1996 which included replacing all furnaces and A/C units as well as installing zoned heating and cooling solutions throughout our homes. They are always highly professional, prompt with excellent service at all times. I would not go anywhere else. Their sales, installation and service teams are first rate! Thanks JonLe!
